[Abstract]

　For Vegetation research, two grazing land sites, one on semi-arid was selected in Pali and another in arid area at Chandan of Jaisalmer. At each experimental site, both herbaceous and woody species were studied as to their composition, cover density and vigor, dry matter production, seed dynamics, and phenology. Mapping of land use and land degradation were carried out using NOAA AVHRR image data of Thar desert area. For socio-economic study, a survey of the awareness for desertification was undertaken at a sample village Khabra Kalan to understand the causal factors between desertification and human activities. To evaluate the influence of the human activities on a sand dune, the 3 dimensional measurement and the usage of the dune was investigated.
